Yunnan Small Bean Coffee: From Terroir to Brewing

Yunnan is China's largest coffee-growing region, providing about 95% of the country's total output. Its small-bean coffee is Arabica, known for a neutral, slightly acidic flavor that suits many palates.

When discussing China's coffee regions, Hainan and Yunnan stand out. Hainan mainly grows Robusta with a darker roast, offering strong impact and heavy taste. Yunnan, however, is the largest producing region and the earliest in mainland China to introduce coffee cultivation. Its coffee areas lie in the southwestern part, between the Tropics, at 1,000 to 2,000 meters. Abundant rainfall, sufficient sunshine, and large day-night temperature differences create favorable terroir for coffee trees.

When talking about China's coffee-producing regions, one cannot avoid Hainan and Yunnan. Hainan mainly cultivates Robusta varieties, often with a darker roast, giving a strong impact and heavy taste. Yunnan, on the other hand, is the largest coffee-producing region in China, the only high-quality coffee raw material production base, and also the earliest region in mainland China to introduce coffee cultivation. In the past, people's understanding of Yunnan mostly stayed with Pu'er tea, and knowledge of local coffee was limited, but nowadays Yunnan beans can be found in almost every cafe. After the movie "A Little Red Flower" was released, more people began to know and deeply understand Yunnan coffee.

Yunnan is China's largest coffee-producing province. Although its output is slightly inferior compared with neighboring countries, its quality is not inferior to coffee from other origins. Yunnan coffee accounts for 95% of the country's total output and is China's main source of coffee.

Yunnan's coffee-growing areas are concentrated in the southwestern part of the province, right in the coffee golden belt between the Tropic of Cancer and the Tropic of Capricorn. The altitude is about 1,000 to 2,000 meters, mainly mountainous terrain with steep slopes and fertile soil, and farmers usually plant coffee trees on hillsides. The region has abundant rainfall and sufficient sunshine, and the high altitude brings a noticeable temperature difference between day and night. Together, these factors create extremely favorable terroir conditions for growing coffee trees and provide a very good growing environment for Yunnan coffee. As people's understanding of coffee gradually changes, Yunnan today increasingly values coffee quality and is slowly entering the specialty stage.

Small-bean coffee is not unique to Yunnan; basically every place in the world that can produce coffee grows it. Now small-bean coffee can be seen everywhere on the streets, but merchants more often use its other name—Arabica coffee.

What Yunnan calls "small-bean coffee" is actually what the market commonly calls "Arabica coffee"; it is just a different naming habit. All Arabica originated in Africa, was later developed by the Arabs, and finally spread to the Americas and Asia. Yunnan small-bean coffee has a relatively neutral taste profile, neither too sour nor too bitter, with a slightly acidic and comfortable style that also suits the general palate.

The "small-bean" variety contrasts with Hainan's medium-bean Robusta coffee beans. Yunnan initially introduced and planted two pure Arabica varieties, Typica and Bourbon. The ancient Typica is recognized as a high-quality variety; the famous Jamaican Blue Mountain coffee belongs to the Typica variety, with rich aroma and refined, diverse flavors, but its yield is extremely low, and it is susceptible to rust disease, requiring more labor for management. Coffee is, after all, a crop that Yunnan farmers rely on for their livelihood. If the yield is too low to meet income needs, it is difficult to sustain cultivation, so most Yunnan farmers choose to switch to a higher-yielding variety: Catimor. Front Street Yunnan small-bean coffee comes from the Baoshan producing area, is washed Catimor, and after medium roasting has nutty, chocolate, and soft plum acidity flavors.

Many customers say they want to taste the flavor of Chinese specialty coffee, and we always recommend first our exclusive Front Street 2013. Yunnan Typica.

Yunnan coffee beans Processing method

Front Street's Catimor includes washed Yunnan small-bean coffee and natural Catimor coffee, and of course, there is also our Front Street Coffee Estate's Front Street 2013 natural Typica coffee.

Front Street brewing parameters for Yunnan coffee:

In order to preserve Yunnan coffee's sweet-and-sour sensation and tea-like characteristics, Front Street Coffee gives it a medium roast. When brewing, you can use a V60 dripper, a 1:15 coffee-to-water ratio, medium grind (about the size of coarse sugar / 75% passing through a Chinese No. 20 standard sieve), and 88°C water temperature.

Use staged extraction, blooming with 2 times the coffee powder weight in water, that is, 30 grams of water for a 30-second bloom. The reason a blooming process is needed is to allow the coffee powder to release its internal carbon dioxide gas, thereby making the later extraction more stable. Pour in a small stream in circles until 125 grams, then pause, continue pouring until 225 grams and stop. After the water in the dripper has dripped through, remove the dripper. Start timing from the beginning of pouring; the extraction time is 2'00". Next, pick up the whole cup of coffee and swirl it evenly, then pour it into a cup for tasting.
